Choice of the optimal rocket shape is a tricky business, even if the rocket with no side boosters is shaped like a rod. If you make the rocket thinner, then the drag area is reduced, but the rocket length is increased, the flowfield is changed for various angles of attack.

In December 2015, tests started for the injectors of our liquid-propellant rocket engine with thrust of 100 kgf. Early hydrotests (flow tests) of the injectors were held in Moscow Aviation Institute (MAI).

Two experimental liquid-propellant rocket engines with curtain cooling, having thrust of 100 kgf each, whose chambers are made of stainless steel, are being prepared for the ground testing. Currently the engines undergo hydrotests, which will be reported on our website.

To improve the engine efficiency and reduce the costs we plan to conduct a series of experiments with various materials. One of the options is the use of heat resistant reinforced carbon-carbon composites. However, they are quite expensive. Therefore, given that the specifications of our engine (temperature, chamber pressure) are quite modest, first we are going to consider the graphite option.

And October 4 is also the anniversary of the private Space Age, because on October 4, 2004 a private suborbital spaceplane named SpaceShipOne reached the space for the second time in 5 days and successfully landed at the spaceport.

Our company participated in IV All-Russian Scientific and Technical Conference "Current Issues of Rocket and Space Engineering". The event is unofficially called Kozlov Conference in honor of Dmitry Kozlov

Long-term human spaceflight and life of explorers at lunar bases are impossible without deep understanding of how human body is functioning and how human psyche is changed during prolonged isolation. Information is notably little about the impact of spaceflight on female body.
